Patent CA-2512897-A1 (CA)
Inventor: LISS RAYMOND M
IPC: H04W36/14
Filed: 2004-01-13
Abstract: To address the need for an apparatus and method for handoff from a cellular wireless network to a non-cellular wireless network (WLAN, e.g.), the present application describes an access gateway (214) and a dual mode mobile station (201) that enable such handoffs. The MS provides information to the access gateway so that it can initiate a handoff with the serving cellular MSC (251).  By triggering handoffs in this manner, cellular networks need not have special information about non-cellular networks to support handoffs. Instead, dual mode MSs can determine when a handoff to a non-cellular network is preferred and request a handin (302) from the non-cellular network.
